It wouldn't make any sense to build both the current Roadster and a new chassis with a straight six.

They could end up with a shed full of V6 engines unsold.

Which is why I think until the end of the Roadster production is announced, they won't build a six version of the new chassis.

And I suspect there will be a gap between to generate demand.

Simple!
